Projections of coral bleaching risk in the Western Pacific under different levels sea surface temperature increases
The collection contains Degree heating week (DHW) time series. The matrix has 4 dimensions : longitude, latitude, time-window and warming). The data are on a longitude/latitude grid from 123 E to 210 E and 25S to 16 N. there are 21 warming slices ( 0 to 2degC every 0.1 degC) and 30y for each warming slice.
DHW is a metric used to measure bleachin... moreg risk due to ocean temperature and is calculated from Sea Surface Temperature (SST) timeseries.
Each 30-year DHW timeseries is associated with a warming anomaly (none to +2oC every 0.1oC). For projections of DHW, warming anomalies are added to detrended SST timeseries.
There is no particular time associated with the 30-year window. Each 30-year window is actually used to calculate probability of heat stress for a single warming slice or time slice of the mean state change. Therefore we are using the 30-year observations of SST to give use the characteristics of the SST variability, rather than a 30-year projection of SST. (For more details see Langlais et al., 2015 Local SST variability determines coral bleaching risk under global warming. Geophysical Research Letter.)
This collection is a single 4.6GB matlab file.

coal bleaching: projections: sea temperature
Generated from NOAA Optimum Interpolation 1/4 Degree Daily Sea Surface Temperature Analysis, Version 2 (Reynolds RW, Smith TM, Liu C, Chelton DB, Casey KS, Schlax MG (2007) Daily high-resolution-blended analysis for sea surface temperature. Journal of Climate, 20, 5473-5496 ). The satellite SST product , known as Reynolds 0.25 v2, was obtained through the Research Data Archive at the National Center for Atmospheric Research, Computational and Information Systems Laboratory. http://rda.ucar.edu/datasets/ds277.7/.
